`Letters Paten-t No. 94,948, dated Sqitem-ber 21, 1869.

f IMPRovED PRoTEcToR FORSTBMS or' BOATS.

The Schedule referred`to in lthese Letters Patent and making part of the same.

y sex,a`nd State of Massachusetts, have made a new and useful invention, having reference to Boats; and do hereby declare" the same to be fully described in the following specification, and representedin the ae- ,companying drawings, of which-I Figure l is a top view, and

Figure 2, a side elevation of a boat, provided with our invention, or elastic saletyfhead.

Figure 3 is a top view,

Figure 4, a side` elevation,

' Figure 5, a rear elevation'of the elastic-safetyfhead.

The purpose of the said head is to preserve the bow or cu-twater of the boat from injury, as well as to prevent it from doing damage to-a vessel, `or other object, againstwhich it may be forced. i

It is citen the case that damage results, either to a boat 0r vessel, byreason of the forcible contact of the cutwater ofthe boatwith the vessel. "Sourietinles the boat, while under the counter of' a vessel, will be thrown upward with' great force by the waves`,so`as to drive the head of the cutwater-agaiust the counter, in` which case injury to the boat or thevessel, or both, generally results, all of which may beavoided by the invention to be hereinafter described.`

In carrying outf'oursaid invention, we fix4 to the bow or the cutwater, or nose, a, ofthe bow cfa boat, A, so as to extend down in front, and over the top thereof, an elastic head or mass B, of India rubber. This elastic head we generally extend down to or a little below the light water-line, and, for the purpose of applying it to advantage, we form it in 'manner as represented in figs.4 3, 4,.and 5.

In these figures, the said elastic 'head is .shown as recessed at c, to receive the nose or c utwater, the' parts al d, which are the Hanks of thereeess, being to tit against the sides of the nose or cutwater, and to be fastened thereto, by screws going through holes. c e e,

made .in the said flanks.

There is, above the recess c, a thick mass or bunter,

j, from which there projects backward a tongue or lip, g. This bunter niay be recessed to receive the head v of' the cutwater, when projected above theA bows. It should be about an inch or more in thickness, in order that it may be sutiicieutly elastic andl durable.A

The lip g is to be provided with holes i, to receive screws, tohold it to the dat surface of the deck, or top of' the bow ofthe boat.

When a boat, of whatever kind it be, is provided with our said 4elastic head, it may be shoved bow forelnos't against an object without danger of injury thereto,`or to the cutwater or bow of the boat. So, when the bowlof the lboat may be under the counter of a vessehtheelastic bunter of the head will prevent chafing of the vessel by th'e head of the cutwater'or bow when the boat is moved upward bythe waves.

The elastic head we construct of India rubber or gutta percha, or an elastic composition of which either is a material constituent.

i We claim the combination and arrangement/of the elastic head B, as described, with the bow orlcutwater of a boat, A, the said elastic head being for the pur poses or objects as set forth.
